Effects of curcumin and the complexes system on the ratios of Bcl-2/Bax and p65 levels in PC12 cells. The PC12 cells were pretreated with curcumin and the complexes for 0.5 h and then exposed to 500 μM H₂O₂ for 12 h. (A) The expression of Bcl-2/Bax, β-actin was used for normalization and verification of protein loading, Bcl-2 and Bax in control, H₂O₂, curcumin and the complexes systems treatments and β-actin representations of the ratios of Bcl-2/Bax; (B) Following the same treatment, the p65 levels were identified. Data are shown as mean ± SD (n = 3). (^# p < 0.01 versus control; ** p < 0.01 versus H₂O₂-treated cells).
